MCM-41-supported bidentate phosphine palladium(0) complex as an efficient catalyst for the heterogeneous Stille reaction

A Stille coupling reaction of organostannanes with organic halides has been developed in the presence of a catalytic amount of MCM-41-supported bidentate phosphine palladium(0) complex (0.5 mol %) in DMF/H2O (9:1) under air atmosphere in high yields. This polymeric palladium catalyst exhibits higher activity than Pd(PPh3)4 and can be reused at least 10 times without any decrease in activity.

The MCM-41-supported bidentate phosphine palladium(0) complex is a highly efficient catalyst for Stille coupling reactions and can be reused 10 times without any decrease in activity.
